The soft switching is applied to the multi-level inverter to enhance the characteristics of HID(High Intensity Discharge) Ballast in headlight of vehicle. The electrical properties are investigated. The available modeling of the ballast in steady-state is calculated using mathematical method and the result is used in analyzing the power characteristics and design of the system. Finally the designed system md modeling is confirmed by the experiment.
